我想成为北京奥林匹克运动会的志愿者。 我感觉时间飞快。我必须努力学习英语。 因为英语是非常有用的并且是很重要的。 对奥林匹克运动会的志愿者是好的为我自己也是。我能和不同的国家交一些朋友和学会更多关于体育,关于奥林匹克。 但第一事 艰苦研究, 我是确信的我意志是一个好志愿者并且我向世界显示:我们的国家和我们的城市是很完善在世界上。
我们等了很长时间，终于实现了！第29界奥林匹克运动会将在我们最大的城市举行．这不仅是一次能展示我们的运动员力量的机会，而且是展示我们国家美丽的最佳机会！
我们现在是初中学生，所以我们可以为奥运会做一些事．我们可以关注环境保护或者积极做些小贡献
我希望第29界奥运会成功举办。
